Just who -- or what -- are the members of Stand For San Jose, a "citizens' group" opposed to the Oakland Athletics moving to San Jose?

They just might be Giants.

The city of San Jose filed a court order to find out more about Stand For San Jose -- and specifically, to see if the group opposing a downtown San Jose ballpark for the Oakland A's is connected to the San Jose Giants, the San Francisco version's minor league affiliate, according to the San Jose Mercury News.

"The perception all along is that it's the Giants who are behind this," said City Attorney Rick Doyle, in comments made to the newspaper.

The Giants opposed from the start efforts by the A's to move to San Jose, the second choice for team owner Lew Wolff after a scheme to construct a new ballpark in Fremont fell apart during the real estate crash, the newspaper reported.

Stand for San Jose sued the city on Dec. 2 of last year, alleging that city reports on traffic and environmental impact were flawed. The San Jose Giants were listed as part of the "coalition," the newspaper reported. The following people are all plaintiffs: "Eileen Hannan, Michelle Brenot, Robert Shields and Fred and Karen Shirey, all of San Jose, and Robert Brown, a Los Gatos resident who works in San Jose," according to the newspaper.

The Giants, per Major League Baseball Policy, declined to comment on the lawsuit or the move.

MLB would have to approve the A's move to San Jose -- that is, when and if a stadium is built, the newspaper reported.
